    Averages

    In the Pacific Ocean Region between January 1990 and Jnuary 2000 there were 82 tsunamis. Calculate the average number of tsunamis (correct to one decimal place) in this period of time.

    Do i divide 82 by 11 or 10 ? im confused

    Thanks, Chhoeuk

    This is a 12 month period. (1 year) So divide by 12.
